Just a heads up, the flanges on the M1 are 12mm (inside measure)/13.5mm (outside), which I believe is the minimum is required if you don't want to notch the bend. The reason for the notching is that the cutouts for the toolless plastic clips that hold the side panel are too close to the bend and there's a risk of it not bending correctly. The first M1 prototype had slightly shorter flanges at the top and required notching, which you can see here (look just above the clips on the top rail). They weren't really a problem in the M1 (though I modified the design anyway to get rid of them), but in your design these notches would be visible from the outside.
Could it be different between aluminum and steel?
